Abstract-- The goal of this research is to resolve the crisis of
energy through efforts to reduce the use of fossil oil fuel (OF).
The specific target to be achieved is to convert the vertical
dynamic load four wheeled vehicles into renewable energy that
can be used as energy reserves. The target can be achieved by
substitution methods that replace the use of fuel energy with
repetitive dynamic load of vehicles passing on the road. The
method used in this study is sucking and injecting the air
outside into the storage tank using vertical dynamic load of
four-wheeled vehicles. Vertical dynamic load is obtained
through a mechanism of flexible portal mounted transversely
on the road surface. The mechanism of injection is done by a
pneumatic cylinder piston which is actuated up and down by
the portal crushed by the wheels (tires) of vehicles. The
compressed air storage process is supported by the installation
of some non return valve and the reducer connection on both
inlet storage tank. Variations weight of the vehicle : light,
medium and heavy that cross the road surface simultaneously
pump the air outside into the storage tank. The amount of
injection pressure of a pneumatic cylinder comes from the
dynamic load vehicles at about 0.3 bar to 0.5 bar. This
renewable energy can replace the use of fuel or electricity to
produce compressed air.
